Log in or register, to view the original The task Laboratory Work Study of Body Movement Under the Effect of Weight Force The goal is to measure the initial speed given to the body in a horizontal direction during its movement under the action of the gravity force.Equipment: stativ with mufty, bulk to launch the ball, fanner board, two sheets of white and one sheet of copying paper, buttons, line, high, millimeter paper, stick strip (if necessary).The course of work.1 .Process theoretical information and instructions for laboratory work.Prepare a data table in the work to record the results of measurements and calculations.The 2ndUsing the stative, fix the fountain plate vertically so that the curved collapse of the roof is horizontal.3 .Close to the fan with the white paper leaf button.and 4.Put the ball on the top edge of the yellow and release it (Ris 2).Find the place of the ball falling on the party.In this place, next to the foundation of the installation, on the party, put a sheet of white paper, and above it a copying, copying ball down.It is appropriate to put a piece of rubber under the white paper leaves to prevent damages to the surface of the party.and 5.Put the ball on the top end of the yellow and release it.Use a measurable strip to measure the distance of the flight of the ball l (see the figure) and the height of the fall h. The results of the measurements will be recorded in the table.6 .The result will be repeated 4 times (points 4 to 5), each time by measuring the distance of flight l. Calculate the average value of flight distance lc = (l1+ l2+ l3+ l4)/4 and the average value of initial speed v0ser = l√(g/2h).No h, m l, m lser, m v0ser, m/s 1 2 3 4 7.Calculate the absolute and relative failure of the experiment.Without the failure of the acceleration of free fall, calculate the relative failure of the initial speed: ε = ∆l/l + ∆h/2h The absolute failure of the initial speed is calculated by the formula: ∆v0ser = ε*v0ser 8thThe results of the calculations are placed in the table.The misconduct % absolute failure ∆v0ser, m/s v0 = v0ser ± ∆v0ser, M/S 9.Make a conclusion in which you will describe your achievements that you have earned by performing this job; the main causes of failures; the main, in your opinion, the disadvantages and advantages of this study; suggestions on its improvement.Do this laboratory work on your own, making a similar installation at home.Enter a photo of your work file.
